CAR-AXLE LUBRICATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 299,321, dated May 27, 1884.

(No model.)

To all whom it may concern:

Be it known that I, WILLIAM S. G. BAKER, of Baltimore, Maryland, have invented certain new and useful Improvements in Car- Axle-Lubricating Devices, of which the following is a specification.

My invention more especially relates to that class of axle-boxes in which the lower part of the box 'is filled with wool waste, sponge, or other equivalent material, which is saturated with a liquid lubricant. My invention may, however, be advantageously applied to axleboxes of other kinds.

In the use of the boxes above referred to it is found difficult to prevent the liquid lubricant from splashing or slopping out at the rear of the box through the opening that admits the journal. Various devices have been contrived for forming a tight packing at this end of the box, and I have illustrated in the accompanying drawings one of my improved spring-actuated washers, which bears against the outer face of the back end of the box. It is, however, desirable that there should be some means inside the box to confine the lubricant therein; and my present invention consists in an improved way of accomplishing this result.

In the accompanying drawings, Figure l is a side view, partly in section, of a j ournalbox embodying my improvements; and Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1.

The box A is provided near its rear end with a vertical partition, B, that extends transversely across the interior of the box, and is preferably concaved or curved at its upper edge, to partially surround the journal 0, but is located a sufficient distancetherefrom to allow the journal to have its necessary play. The lower edge of the partition is located somewhat above the bottom of the box, so as to leave acommunication, a, between the main portion of the box and the chamber b, formed by the partition and the rear end of the box. The communication a should be below the level of the oil in the box, so that the lubricant may readily pass from one chamber to the other.

Within the chamber 1) is apad, D, of felt or other suitable absorbent material,that extends across the box from one side to the other and from the bottom of the box to the journal, and

partially surrounds it, as illustrated in Fig. 2. I preferably provide the pad with a spring, 0, which permits it to yield to the play of the journal, but holds it at all times in close contact therewith. A lug or ridge, d, is formed on the rear inner end of the box, to support the pad at about its middle and hold it away from the rear wall of the box, so that the lubricant will not scrape off and flow through the rear opening.

By the improved organization above set forth the rear end of the journal is lubricated by the oil absorbed by the pad D from the oilchamber, and any lubricant that may tend to flow out at the rear of the box will be caught by the absorbent pad and returned to the main lubricant receptacle or cellar E, to be again used, whereas in boxes in which the transverse partition forms an entirely separate chamber, With no communication with the oilcellar, suchchamber would eventually become filled and overflow through thejournal-opem ing, and in those boxes that are provided with a separate chamber at the rear of the box, and a communication between such chamber and the main oil-receptacle, the oil will rise to the same level in both chambers and tend to overfiow through the j carnal-opening, In my improved organization, in which the supplemental chamber is filled or closed by an absorbent pad, any splashing or slopping out through the rear end of the box is prevented, and that part of the journal in contact with the pad is thoroughly lubricated by the lubricant absorbed from the main receptacle, as well as by what the pad catches when the liquid tends to flow out at the rear of the box.

I claim as my invention- 1. The combination, substantially as set forth, of the box, the transverse partition located near the rear end of the box, an opening formed in the partition below the level of the lubricant in the box, whereby a communication is established between the front and rear chambers formed in the box by said partition, and the absorbent pad located betweenthe partition and the rear end of the box, which lubricates the journal at that point and returns to the main receptacle or cellar any excess of I00 lubricant.

2. The combination, substantially as set forth, of the box, the journal, the pad applied I away from the rear end of the box.

3. The combination, substantially as set forth, of the box, the journal, the pad, the spring which holds the pad against the journal and permits the pad to be compressed to allow for the play of the j ournal, the lug formed 10 on the box,which holds the pad away from the rear wall of the box, the chamber in which the pad works, and a communication between said chamber and the front of the box.

In testimony whereof I have hereunto subscribed my name this 23d day of February, A. r 5
